Implement CanvasRenderingContext2DBase::drawImage() for a WebGPU source

Reviewed by Mike Wyrzykowski.
Most of the plumbing was already in place.
GPUCanvasContextCocoa::surfaceBufferToImageBuffer() and
transferToImageBuffer() just needed to return an ImageBuffer with the
WebGPU canvas color space, and PixelFormat::RGBA16F if it was configured
to show an extended color range.
The new test also revealed a small latent issue, where an obsolete
compositing result was output in the image buffer despite
m_compositingResultsNeedsUpdating being true.
